start/stop, check and verify Cluster
clstart -m -s -b -i -l
smitty clstart
start Cluster service
smitty clstopt
stop Cluster service
clstop -f -N force shutdown cluster immediately without releasing resources
clstop -gr -N graceful shutdown immediately with takeover
lssrc –g cluster check Cluster service daemons
clverify verify and sync the Cluster
cldare -t sync the cluster topology
cldare -t -f mock sync of topology
cldare -r sync the cluster resources
cldare -r -f mock sync of resources
delete Cluster
usr/es/sbin/cluster/utilities/clrmclstr be very carefulldelete the cluster completely
Topology Information
lslpp -Lqc cluster.es.server.rte | cut -d: -f3 there is no specific command to get the PowerHa version,but the version of the cluster.es.server.rte refects it.
lssrc -ls clstrmgrES \
| egrep "local node vrmf|cluster fix level"
If you do not trust the above Information, you could ask the cluster manager to display the version
cllsnode list the info about the cluster nodes
cllsnode -i NODENAME list info about node NODENAME
lssrc -ls topsvcs show heartbeat information
lssrc -ls grpsvcs show all info about group
cllsif list adapter information
cllsnw list network information
cllsnw -n ETHER1 list the details of network ETHER1
clstat find the status of cluster
clgetif list interface name/interface device name/netmask
associated with a specified ip label / ip address
of a specific node
cllsparam -n NODENAME list the runtime parameters for the node NODENAME
clgetip RGNAME get the ip label associated to the resource group RGNAME
cllsnim show info about all network modules
cllsnim -n ether show info about ether network module
cllsgrp list all resource groups
cllscf list cluster topology information
cltopinfo list detailed information about the network of the cluster
cldisp list detailed info about the cluster (not realtime)
cldump list detailed info about the cluster (realtime, shows cluster status)
clfindres find the status of resource group
clshowres find the properties of a resource group
clshowres -g'RG' show resource information by resource group
clshowres -n'NODE' show resource information by node
cllsdisk -g RGNAME list the PVID of the shared hard disk for resource group RGNAME
cllsvg list the shared vgs which can be accessed by all nodes
cllsvg -g RGNAME ist the shared vgs in resource group RGNAME
cllslv list the shared lvs list the VG of LV
cllslv -g RGNAME list the shared lvs in the resource group RGNAME
clgetvg -l LVNAME list the VG of LV LVNAME
cllsfs list the shared file systems
cllsfs -g RGNAME list the shared file systems in the resource group RGNAME
usr/es/sbin/cluster/utilites/cldare –M RG NODE -N -v move a Resource Group (RG) to another Node

Extend a VG in HACMP

configure disks

After running cfgmgr provide the PVID on both the nodes
1st Node
aixpA:># lspv|grep hdiska
hdiska none None
aixpA:/># chdev -l hdiska -a pv=yes
hdiska changed
aixpA:/># lspv|grep hdiska
hdiska 00f32304c974dc21 None

2nd Node
aixpB:/># lspv|grep hdiska
hdiska 00f32304c974dc21 None
aixpB:/># chdev -l hdiska -a pv=yes
hdiska changed
aixpB:/># lspv|grep hdiska
hdiska 00f32304c974dc21 None

Run Discovery on any node

since HACMP need to know the latest changes on the Nodes
smitty HACMP-> Extended Configuration->Discover HACMP-related Information from Configured Nodes

This process wil take about 5-10 mins or may be faster

add new disk to Shared Volume Group

Smitty hacmp->System Management (C-SPOC)->HACMP Logical Volume Management->Shared Volume Groups->Set Characteristics of a Shared Volume Group->Add a 
Volume to a Shared Volume Group
